  • […] Second thing is getting a capture card that records the resulting 1080p och 720p output from the ADC. I got a relatively cheap one which then plugs into the pc with usb-a. […]

    I want to capture interlaced — not progressive [2][1]. I don’t want any deinterlacing done by the capture card [3].

        Deinterlacing is the process of converting interlaced video into a non-interlaced or progressive form. […]


  • […] First thing to do is to convert the analogue signal to hdmi. […]

    Why? What’s wrong with directly capturing composite? I have yet to come across an HDMI capture card that doesn’t process the signal in some way (eg no upscaling, no deinterlacing). I’m doing this for archival purposes so I want the signal as unadulterated as possible. This also includes these sorts of transformations you mention:

    […] After that i setup a scene with the capture card as source and transform the output using obs to get the resolution, size and format i want. […]
